How to catch the “Call to undefined method” error in PHP 7?

Question

I use my own simple error handling and can actually catch&log everything I need. But now I need to catch an error with try{}catch(){} . The error, that I expect occurring sometimes at that place, is the "Call to undefined method" error. I can catch it like this:

try {
    $someObject->someMethodTheObjectDoesntProvide();
} catch (Error $e) {
    // do something else
}

But the Error class in the catch clause is a bit to generic. I'd like to catch only this type of error.

Is there a way to restrict the catching to a particular "type" of errors?

_{Without using strpos($errorMessage) ... ;)}

Answer 1

Using a magic __call() method in your classes can be used to throw custom exceptions if a method doesn't exist

class myCustomException extends Exception {
}

class someClass {
    public function __call($name, $arguments) {
        if (!method_exists($this, $name)) {
            throw new myCustomException($name . ' has shuffled the mortal coil');
        }
    }
}


$someObject = new someClass();
try {
    $someObject->someMethodTheObjectDoesntProvide();
} catch (myCustomException $e) {
    echo $e->getMessage();
}

我知道我已经超过18个月了，但是你考虑过做@Mark Ba​​ker的建议，而是抛出一个BadMethodCallException ？
